Hey everybody. I would greatly appreciate your help with the following issues.

I got a new AT&T 8820 last week (from amazon) and went through the enterprise activation process with my company -- a process which had been very simple and effective with my 8700c.

After two days of trying, we cannot get e-mail to sync wirelessly after activation. E-mail does a "one-time" sync as of the time of activation but no e-mails which arrive at the server thereafter show up. Contacts sync fully initially as well but calendar does not. The BES admin says he does not see any attempts by my device to access the server (and the server cannot "see" my device). For what it's worth, the device shows a completed activation.

6) Numerous attempts to activate the device both wirelessly and when connected to Desktop Manager on my laptop (with my company VPN and Outlook open).

Two funky things have been happening along the way:

1) Through all the wipes and the OS reinstall, the device always asks for a password at start-up (depending on which troubleshooting was attempted, it either asks for the existing password or asks me to create a new one). My company's Blackberry guy says this is unusual and may indicate a corrupt certificate (but shouldn't that have been cleared up by the OS reinstall?).

2) After completing Enterprise Activation, the "Enterprise Activation" option disappears from the Settings>Options list. The only way to access it thereafter is through the setup wizard.

Any suggestions on how to get this thing set up properly? Should I just return it to AT&T/Amazon for a new one ? I will be around for a couple of hours this morning monitoring responses to provide addditonal info if needed. Thank you in advance for nay help.

I had the same problem this past week with my new curve. ATT had me on a personal blackberry plan instead of enterprise. Call them and tell them to put you on the enterprise bes plan and things should work right away.

Thanks to you both. That was indeed the problem. Device is functioning properly now.

When I purchased the phone online from Amazon, the only data options offered were personal tethered or untethered (and I had to select one). To Amazon's credit. they did say to call your service provider to verify the data plan (which I did) -- but if I remember the language of Amazon's suggestion correctly, it was more to make sure that the purchaser didn't end up paying for two data plans. When I called, my existing plan (which worked with my BES) apparently was the one which was deleted and the personal plan through Amazon was the one left active.
